Okay, I should clarify. For the most part, it does work. It's always been reliable, so I was surprised that it glitched yesterday. And that's my general feeling with this update - in the past, everything has been super fluid and crash-free and so every little glitch stands out.

The calendar is completely unusable for me. I have an all day appointment set for today (thursday). Yesterday (wednesday), the live tile told me that the appointment was on wednesday, while the lock-screen (correctly) stated it was on thursday. Today (thursday), the lock-screen incorrectly tells me the appointment is "tomorrow", and the live tile doesn't mention the appointment at all, instead listing an appointment for tomorrow.

I can't believe how badly they messed up something as essential as notifications for appointments.

Working fine for me. I have the tile and lock screen both saying I have event tomorrow Friday. I am using Hotmail here. I think back in the days I type an event on phone and it sync to different date on the web, or using the WLMail. I don't recall the exact thing. I haven't experience this for a long time and not experiencing this on 8.1 as well.

I do know it is annoying that the calendar cares about time zone. It sucks when I set, my travel plan say, 12pm for lunch, I meant the local time when I get there in the future. Not the 12pm in the time zone I created the event. Setting to the global time it bad IMO. The events are always created as local time, no matter where the person is. The global time is annoying.

@MasterPi:I will keep watch. Ironically my bro's iPhone4 has the same problem. For few days, he didn't get any voicemail and his client said he called and left the voicemail. Then, he found some forum telling to reset the network or whatever to fix it.

@PeterF:In WP8, code have to be written for Apps to support bluetooth. Win8.1 seems to remove this limitation by supporting bluetooth keyboard, mouse, etc., reflected by update to SDK documentation on supporting bluetooth device.

Oh and some good news: XBox Music is going to get 100% better on May 6th.

I don't want to nerd-bash, but if that is the guy who was in charge of music on windows, I'm not surprised it sucks so bad.

Here's an idea, MSFT: the app has 'MUSIC' in the title. Users who run the app want to hear MUSIC. Perhaps you could focus on making that happen before you find some other clever new way to copy iTunes.

So I installed WP 8.1 onto my 920. So far so good. Then I go and use the new podcast app. Horrible!! Not gonna repeat what others have said, but I'll add a new one. Why can't I just download separate episodes? I first have to subscribe before they even let me download. Why do I have to subscribe? Do I just not know how to use the new podcast app?

Oh and the stupid new XBox Music terms popup. I don't have a Xbox and I don't care to buy music on the store or whatever. I don't care about the terms. I click cancel, but it comes up everytime I want to listen to music which I own and put it on the phone. They should have a separate music app thats not associated with Xbox Music.

I love my 920 and so far WP 8.1 is a step up, but this update is not enough for me to stick around with windows phone. The experiment is over for me.

You can turn off Xbox Music from the settings within the app. But, you are right, they shouldn't force you everytime. It should default with Xbox Music Off. It should have a button in the menu says "enable XboxMusic after sign-in". Clicking it will ask for account sign in. Failure will just be back as usual. Success will enable Xbox Music. That would be so much better IMO.

I received an phone update (a major one that required reboot) last week and found that after installed that, the WiFi connection becomes very unstable (have disconnections even at home, never happened before) My brother and sister who uses Andriod does not have that problem so I think the problem is not at my wireless broadband router.

I used the highly compressed mode on IE, but, it doesn't seem to save whole lot of data. And the worse is, it is buggy. For example, it rarely shorten the page, and when it does, it is suppose to indicates the page is cropped. And press the blue button to waste even more bandwidth to download the same page. Here is the bug, sometimes the blue button doesn't appear. So, I am stuck with wasting bandwidths on downloading the cropped page and have no access to the full content.

New beef. They are hiding LTE symbol into Notification Center. Not good.

Edit: It is ok now. LTE is hidden because WiFi is connected. Not sure why they do this. I don't think people would figure this out right away and blaming MS for strange decisions. The design is sound, but, not intuitive.

Well, this is a dead beef, but, not only the WP8.1 IE video control can be removed by developer, the video actually doesn't play correctly. For example, open an embedded YouTube video on Gamespot forum. Press play. Press the completely redundant FullScreen button. Rotate to landscape mode. Now, here is the epic fail.

The video will likely not fit the screen properly. Some of the video will be outside the screen. Then, rotate back to portrait and back to landscape, wasting precious seconds that are extremely hard to get back on the stupid slider control, it will TEMPORARILY fix the abysmal broken video display. At any random given moment, the video will resize again with parts of the video outside the screen.

Photos "Hub" no longer has direct access to friend's photos from Facebook, it links to a separate app now. People "hub" (now "me" I guess) no longer allows commenting or liking Facebook posts -- again, have to open a separate app now. And the messaging app removed the integration as well, and now only does SMS.

All of these things were key features which drove me to buying a Windows phone. If I wanted to stick with the app-centric paradigm of iOS, I would have upgraded my iPhone and stayed with that. WinPho 8.1 seems to be removing things that differentiate Windows Phone from iOS and Android. Let me guess -- was having things integrated "too confusing" for some people requiring gutting of the things that make Windows Phone what it is?

I bought my Lumia 1520 less than 2 months ago and absolutely love it -- and everything I've been ranting to my friends about with regard to why they should buy a Windows phone is going away, including capabilities which sealed my decision to buy one.

I'm not sure how I can see this in any other way than a product, that I already bought, having capabilities removed from it after the fact.

Nice job breaking it. If this keeps up, maybe this awesome Windows Phone will eventually be down to just a grid of apps just like iOS. Why even bother keeping live tiles at this point?

@Craig_Matthews: I understand not wanting to lock the OS into supporting those features. There were some problems when Twitter or Facebook changed the API, and they had to roll out an OS update. However, they should have come up with some kind of plug-in model that would have provided the same functionality.

That's exactly what they need. I certainly get maybe not tying the phone's OS to specific named services (e.g. Facebook, Twitter), but a plug-in model that you suggest would solve the problem nicely and obviously open it up to more than Twitter and Facebook.

The integration of everything from different places into hubs is most of the reason I bought this awesome monstrosity of a phablet and it's an example of where, IMO, devices should be going in the future. Having to go into the Facebook app when I want to bring up the photos from a friend's trip is going to definitely feel like a step backward into the "iPhone way" of doing things.

IMO, Windows Phone 8 is pretty much what Android wishes it was, and makes the iPhone look like a feature phone because WP8 is all about bringing all your stuff into your device in a consistent and useable manner. Now it seems they want to go in the iPhone direction unfortunately. That's a real shame because this phone, as it is, kills.
